such Vas will enable others slrilledin the art I to which it appertainsto make and use the same.

This invention relates to an improved coal grate and one object of theinvention is to provide a grate which may bey formed in a plurality ofsections connected in Van im-V proved manner and producing a grate whichwill be. securely held in the set upposition whenin use. a Y. y

Another object of theinvention is to provide an improved construction ofbottom Ygrating and improved means for mounting this grating forhorizontal swinging movement when shaking a fire, the grating beingpivotally mounted and supported in an improved manner and further somounted that while it may be easily removed and put in place whendesired, it cannot readily become accidentally knocked out of'place.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a view showingthe improved grate in front elevation andplaced within a fireplace. Y

Fig. 2 is a vertical sectional view taken along the line .2 2 ofFig.j1.`

Fig. 3 is an enlarged vertical sectional view taken along the line 3 3of Fig. 1.

Fig. 4t is a vertical sectional view taken along the line 4- 1 of Fig.3.

Fig. 5 is a transverse sectional view taken along the line 5 5 of Fig.3.

Fig. 6 is a perspective view of the bottom grating Vof the grate.

This improved grate is provided'with a `lire box having end walls 1 and2, a front wall 3 and al rear wall 4. The end walls 1 and 2 are extendedbelow the front and rear walls to provide supporting feet 5 and the endwalls are provided with inwardly extending ledges 6 which taperrearwardly and provide supports for the bottom grating 7. This grating 7rests upon the supporting ledges and is provided at its rear or innerend with a notch 8 to receive the pin extension 9 of the rear wall 4.This pin extenup position.

sion provid-es a fulcrum Vto pivotally mount the bottoni grating thuspermitting the bottom grating to befoscillated horizontally by means ofthe handlel extension .10 at its forward end. This handle extension 10will be grasped by means of a suitable shaker (not shown) and ashescanthus'be readily caused to pass through the slots of the grating. Alug 11 is provided .to the i'ear of the handle extension 10 and thefront wall is providedV intermediate its length with a notch 12sothatthe grating can be put in place beneath the front wall. When thisgrating is put in place, the lug passes through the notch 12 and bymoving the grating to one side, the lug can be moved Y out of directalinement with the notch thus preventing any danger of the grating`being accidentally moved forwardly out of the proper position. v Theend'walls 1 and 2 are provided at their forward ends with hooked armextensions 13 for engaging the upper side portions of the front wall andthe front wall is provided withvarm extensions 14: for engaging thelower forward portions of the end walls 1 and 2. Arm extensions 15 areprovided at the upper vrear end portions of the end walls to engage therear wall, and arms 16 are carried bythe rear wall for engaging the endwalls 1 and 2. Fastener bolts 17 pass through the arm extensions andthrough the walls so that these walls may be securely but releasablyheldin a set- It should be noted that these walls are firmly heldagainst any movement when the bolts are in place and therefore the gratecannot become distorted.

The end wall is provided with rearwardly extending side flanges 2O forengaging the rear or inner wall of a fire place and further has itsupper portion 4 inclined outwardly to overhang the tire box as shownclearly in Fig. 3. From an inspection of this figure, it will be seenthat the rear wall together with its side flanges 2O and headplate 21will provide a box-like structure when the grate is in place thusproviding an air chamber in which air may accumulate and pass outthrough the openings 22 formed in the rear wall. The openings 22 formedin the lower portion of this rear wall are provided in rows between theribs 28 which taper upwardly and will serve to hold the coal in spacedrelation to the rear wall. Therefore, air can pass into the fire-boxfront wall and the tongues 14 engaging the through the openings22Yformed in thelower portion of the wall 4 and of course, may also passinto the re-boxthroughthe usual openings 24 formed inthe walls ofthe-re-box.

- In addition, a'portion of the air in the air chamber at the rear ofthe grate will pass out through the openings in the upper portionof thewall 4 and this air which discharges from the air chamber abovetheVfire-boX will serve to drive the heat from the fire out into theroom, the inclined upper portion 4 of the wall 4 serving` as adeflecting surface.

`When this grate is 'to beused, it will be V assembled as shown with thetongues 13 of the end walls engaging' the outer face of the outer facesof the end walls .The securing bolts for these tongues will be put inplace and the `end walls .will then jbe. connected with the side flanges2O vof the rear -wall by passing bolts through the slotsYV of thetongues l5 and 16 carried by the end walls and rear wall. The bottomgrating will be put in place and the grate is then ready to beinstalled. When the grate is placed in the fire-place 25, 'the flangesor walls 2OV and the head-plate 2l will engage the inner'wall 26 ofthe'fire-place and thus vprovidethe` air chamber tol receive the airwhich is to be fed into the fire-box through the rear wall 'and v whichis to pass through the openings in vthe overhanging upperpoition of thisrear wall. l The lire will be started and asthis fire vburns, theoverhanging upper'section of the rear wall will provide a deflector'surface and the air passing through the openings in this overhangingupper portion of the wall will serve to drive the heat out into theroom. The ribs 23 serve to prevent the coal Vfrom accumulating in therear portion of the 'fire-box against the rear wall and therefore therewill be no danger of the openings iii Y this rear wall becoming stoppedup by ashes. vWhen it is desiredl to lshake the fire, it is simplynecessary to grasp the handle extension lQ'and oseillate the'grate withthe pin 9 serving as a fulcriun point. If it is desiredv Vto dumpthegrate, it is simply necessary to drawv the grate y outwardlythroughthe space beneath the frontj wall and the contents of the fire-box maydrop down upon the hearth. A grate for an open fire-place has thus beenprovided which can be easily andquickly put together or taken'apart ifnecessary.
